adjusting bolt and screw, or the oil reser-
voir with your bare hand or skin until
suspension components have cooled.
 Always adjust the shock absorber as-
semblies on the left and right side to the
same setting. Uneven adjustment can
cause poor handling and loss of stability,
which could lead to an accident. Notes on adjusting the suspension
A special wrench and special tool can be
obtained at a Yamaha dealer to make the
spring preload or crossover setting adjust-
ment.
 When adjusting the damping force settings,
turn the adjuster in direction (a) until it
stops, and then count the turns or clicks in
direction (b).
 Although a damping force adjuster may
turn or click beyond the stated minimum
settings, such adjustments are ineffective
and may damage the suspension.
NOTICEECB00091Never turn an adjusting mechanism be-
yond the minimum and maximum settings. Spring preload
1. Elevate the vehicle and place a suitable stand under the frame.
2. Loosen the locknut.
3. Turn the spring preload adjusting nut in direction (a) to increase the spring pre-
load and thereby harden the suspension,
and in direction (b) to decrease the spring
preload and thereby soften the suspen-
sion.
